Library

As a time traveler, the first problem Ludwig struggled with was neither money nor power, but language. It is difficult to learn an alien language from scratch. Fortunately, he has abundant conditions. An endless huge library, plenty of food and water, two years of free time, --There are even visitors of all shapes and sizes accompanying him to practice speaking. However, on the back of the door, there were words imprinted on it that he would never see. "This is a stasis library that collects all the tellable and unspeakable knowledge in this world. You will see everything you want to see. The price is that you must offer your loyalty to the supreme lord of this place. That lord, the foreigner, will come in a thousand years. The life of a mortal is short, lasting no more than a hundred years. You can't see his true face, but his dense bones will become his ladder. Burn everything you have. It's worth it, he will use your ashes to smear the ruined world. "
